TEMPLATE Fon application med .Tune e',

This invention relates to templates for guiding routing machines, and has especial reference to meansfor guiding the tools thatcut the recesses and slots for the lockfronts, knob-shafts and keyways, of door locks. j

The object of the invention is vto provide two similar .template members, which are connected and arranged for guiding a lrouter in different planesand in different directions relatively to the lock mortise, one of said members being arranged for ciamping the combined device to the edge of a door, the said clamping means being adjustable to suit doors of different thickness, the said member adapted to overlie the edge of the door, and being equipped with adjustable meansl for gauging the length and breadth'of the recess that receives the front of the lock; the second template member being supported solely by the first member, and arranged to overlie one face of the door adjacent the said edge, said second member being adjustable in different directions relatively to the first member, and being provided with mortise or profiling gauges, the gauging means ofthe second member being adjustable, forvarying the location of the knobshaft and keyhole relatively to the edge of the door and Ythelock frontrecess, to conform to locks of different styles and sizes. And a further object is to provide a combined router support andvguide which may be readily and accurately adjusted for performing the aforesaid routing work for any lock of given dimension and style, before the device is clamped to a door.

I attain these objects by the means set forth in the detailed description which follows, and as illustrated by the accompanying drawings, in whiclr- Figure l is a broken edge view of a door, to which my combined template is applied; showing a front face view of the recess tem', plate, and an edge view of the knob-shaft andkeyhole template. Figl 2 is a broken face view of the door; showing one edge of the recess template and a front face view of the knob-shaft and key-way template. Fig. 3 is a similar side elevation of the door, to the edge of which is applied the recess template, the latter being` in longitudinal section taken on line 34-3 of Fig. l; also showing the door mortised for the reception of a lock, and a. routing tool in the act of cutting the loclsfront recess.

of the door, and a central longitudinal section of the knob ,and key template, the said section taken on line 4-4 of Fig. 2; showing the routing tool in the actof cutting a common slot forv the play of the knobsshaft'and key relatively to the mortise .and recess. And Fig. .5 is a broken end elevatioiiof the combined template, showing the same clamped to the door.y

In the drawings, the template members are respectively designated by the characters A and B. 'Referring to thetemplate A, 2 represent-s achannel-shaped oblong frame or body. having a relatively large medial opening 2 for facilitating the routing work, that lies between web portions 2, as well as between flanges 2, the said web being correspondingly recessed centrally, as the 2?' (see Fig. 5), to receive longitudinally arranged gauge members 8,tliat regulate the length of the lock-front recess, as 3', of the. door 'D (see Fig. 3,). 4 represents similar plates that overlie. the outer ends of Vthe webs 2a, said plates being rigidly fastened to the webs by screws 4', andv said plates being perfoif ated, as at 4a, to receive screws 4b,that are threaded in Vthe webs, land play in slots `3 of the gauges 3, for rendering the said guages adjustable, and for fmaintaining the said adjustments.` The free ends of the plates- 4 are 'formed withy similar' spaced loops 4G, the corresponding lateral edges of the said plates extending beyond the plane V of the corresponding flange 2C, and being slotted transversely, as at 4d.. The clamping means comprise similar fingers or arms 5,

' arranged' in pairs, which are` adjustably mounted -upon right and left hand threaded bolts 5', said fingers being, disposed at the opposite sides of the loops 4C, and being movable towards and. away from said loops and .adaptedto engage the opposite faces of doors of different thickness'. The bolts 5 are inanipulated by knurled heads 5a. The plates 4 only partially cover the websl2a, and upon the facing ends of said webs are adjustably mounted similar recess gauges 6, which` bridge the opening 2', said gauges being movable towards and from each other for regulating the breadth of tlierecess 3, by means `of screws 6', which play in transverse slots 6"', of the gauges, thel said screws being threaded into webs 2n, The gauges 3 are formed at their facing ends with cross bars or heads 3b and these bars are arranged to overlie and slide upon .the gauges 6, as

shown in Figs. 1, 2, 3 and 4. One or both ol the gauges 6 may be provided with a scale, as shown in Fig. 1, for determining the exact length of the recess 3. The opposite ends of the gauges 6 are similarly slotted and the slotted portions extends through and play in longitudinal slots 6l formed in the flanges 2C.

The template B comprises a similar frame or body 7, having a relatively large medial opening 7', and end webs 7a, the said webs lying between and connecting side flanges 'IIb-7c, which extend beyond the webs, said webs being recessed, as the 7d, to receive longitudinally movable gauge members 8, that are held in the adjusted positions by screws 8', which are disposed in countersunk openings 9, of similar plates 9, the latter partially overlying the webs 7a and being rigidly secured thereto by screws 9a. The projecting` ends of flange 7b are slotted longitudinally as at 7 (see Figs. 1 and 4), to receive bolts 10 which play in the slots 4d and 7e, for facilitating the adjustment of t-he template B relatively to template A and the door. The plates 4 and the rail 7b may be normally spaced by sleeves 10. Grdinarily these sleeves are provided in different lengths, in order to suitably space and render rigid the frames A and B, when the latter are adjusted for routing knob-shaft and key openings for locks of different size. The breadth of the common knob-shaft and key slot, as 12, is regulated by a gauge member 1B that comprises an oblong sheet metal body 13, which ispreferably narrower than the space between the flanges 7b-7c, for facilitating lateral movement of'said body within a relatively broad range, said body being 'formed with a longitudinal slot 13, through which a routing tool, as 14, may be inserted and play. The opposite ends of the gauge 13 are preferably formed with similar T-heads 13b, which are slotted7 as at 13", the said heads being adjustably mounted on the webs 7a, between the plates 9 by screws 13d, and the said heads'being arranged to be moved laterally by means of slots 7X, that are formed in the flanges 7"- 7, The body 13 of the gauge 13 is preferably arranged to lie in al higher plane than the gauges V8, and the base, as 14', of the motor 14L is usually narrower than the'spacing of flanges 7b and 7, and preferably slides upon the elevated body 13, while the tool 14 performs the routing work. The gauges 8 are also preferably T-shaped, and their heads 8a are of such breadth as to effectively gauge the length of knob and key slots 12, in case the latter are located at diii'erent distances from the edge of the door, or in dit ferent positions relatively to the lock mortise, as 12', as may be understood by consulting Figs. 2 and 4.

The recess 3 shown in Figs. 1 and 3 may be routed by a tool 15, driven by a motor 1:3', the motor preferably being supported by a plane base 15a, that ordinarily slides over the free edges of the flanges 2C, as shown in Fig. 3.

Bv adjustably connecting the templates A- and supporting the template B solely by the template A, the routing of the recess 3 and the slot 12 may be effected by a single application of the templates to the door, and owing to the adjustable nature of said templates and their respective gauging members 3-6 and 8-13, the exact location as well as dimensions of the recess and slot for locks of any style or size may be-predetermined and the several gauging members may be adjusted and set in advance oli' the application of the combined device to the door. By this arrangement considerable time and labor maybe saved, and more rap id, accurate and reliable work may be `effected, than would be the case if the tem plates A and B were installed separately.

Furthermore, by combining the two templates as herein shown, but one set of clampsV is required.

Having thus described my invention, what I claim is- 1.
